Examination of the Rectum is done by use of?

Appeared in: IGNOU Post B. SC. Nursing entrance-2019

Explanation

A proctoscope is a medical instrument used for the visual inspection of the rectum.
It is a short, rigid, hollow tube, often with a light, designed to examine the anal canal and the lower part of the rectum.
Proctoscopy allows for the detection of conditions such as hemorrhoids, polyps, inflammation, and sources of bleeding within the rectum.

Option A: An autoscope, more commonly known as an otoscope, is designed for examining the external auditory canal and the tympanic membrane (eardrum).
Option C: An ophthalmoscope is used to visualize the interior of the eye, including the retina, optic nerve, and blood vessels.
Option D: A fetoscope is an acoustic device, similar to a stethoscope, used specifically for auscultating (listening to) the heartbeat of a fetus in utero.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of medical instruments for specific examinations as background academic context rather than a clinical decision trigger.
Nurses play a key role in preparing patients for a proctoscopy by explaining the procedure, ensuring informed consent is obtained, and positioning the patient correctly (typically in the left lateral or knee-chest position).
During the procedure, the nurse assists the provider, monitors the patient for discomfort or adverse reactions (like a vasovagal response), and provides reassurance.
What if? If the examination needed to visualize the area beyond the rectum into the S-shaped part of the colon, a proctoscope would be insufficient. A longer, flexible instrument called a sigmoidoscope would be required.

How to Approach the Question

First, identify the key terms in the question: 'Examination' and 'Rectum'.
Next, consider the function of each instrument listed in the options.
Evaluate Option A (Autoscope): Recall that 'oto' relates to the ear. This is incorrect.
Evaluate Option B (Proctoscope): Recall that 'procto' relates to the rectum or anus. This is a likely candidate.
Evaluate Option C (Ophthalmoscope): Recall that 'ophthalmo' relates to the eye. This is incorrect.
Evaluate Option D (Fetoscope): Recall that 'feto' relates to a fetus. This is incorrect.
